ATTACHMENT FOR GGLF CLUBS.

Application filed March 19, 1926. Serial No. 95,871.

This invention relates to games and has special reference to golf clubs.

The center oi gravity of golf clubs varies in position from seven to iii'teen inches up from the heel of the head. This variation occurs to some extent even in clubs for the same purpose and made by the same person or manufacturer. Consequently the user of a club, becoming accustomed to the balance of that particular club, is thrown oii his play upon using a club with a diiierent balance such as is caused by a variation in the position of the center or gravity.

()ne important object of the present invention is to provide an improved form of goli club having means whereby the center oi? gravity may be adjusted to suit the individual player.

A second important object of the invention is to provide an improved attachment for goli. clubs whereby the center of gravity may be raised or lowered as desired by the player using the club.

Qt is well understood that, other things being equal, the more nearly the center of g avity can be brought to a low point the 'eater the centri'tugal force developed in the swing of the club which materially aids in long drives. Also, by concentrating the v; eight towards the head "he tendency will be to hit the ball in the center of the face rather than toward the too, such concentration or weight also aiding to cause the head to travel in a plane so that cutting the head across the ball is prevented.

A third important object or the invention to provide an improved attachment for golt club heads which aids in concentrating weight at a low point on the club.

With the above and other objects in view as will be hereinafter apparent, the inven tion consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

in the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 is a side elevation of the lower portion of a golf club head showing the attachment in place.

Figure 2 is an enlarged section on the line 2 2 of Figure 1.

In the drawing it will be seen that the club shown has a head from which a metal shank 11 extends of an angle, this shank being of less diameter adjacent the head and being taperingly enlarged upwardly to the point at which it joins the wooden shaft 12,

this being the ordinary construction of such clubs.

The attachment consists of a heavy metal ring formed o1 two halves 13 having their ends provided wi rabbcted overlapping portions 1% through which pass the set screws 15 which not only hold the two halves together but which bite into the material of the shank 11 when adjusted thereon so that the ring may be secured in any desired position on the shank. Obviously the interior of the ring is tapered to conform to the taper of the shank end, when used on the narrower part of the shank, may have an internal liner or shim 16.

By means of this attachment the center 0t gravity of the club may be adjusted within limits since the lower the position of the ring the lower will be the center of gravity of the club as a whole.

There has thus been provided a simple and eiiicient device of the kind described and for the purpose specified.

Having thus described the invention, what is claimed as new, is:

1. The combination with a goli club having a head and shank; of a weight ring slidably mounted on said shank to move toward and from the head, and means to hold the ring in adjusted position on the shank.

2. The combination with a goli club having head and shank; of a ring slidably mounted on the shank to move toward and from the head, said ring consisting of arcuate sections provided at their ends with overlapping rabbets, and set screws passing through the overlapping rabbets and engaging the shank.

3. An attachment for golf clubs consisting of a ring formed of a plurality of arcuate sections having interengaging ends, and setscrews passing through the interengaging ends to hold the parts of the ring together, said set screws being adapted to project interiorly of the ring to engage the shank of a golf clubhead.

in testimony whereof I aiiix my signature.
